MOSCOW (AP) - Russia's foreign minister is rejecting U.S. demands to extradite National Security Agency leaker Edward Snowden, who has apparently stopped in Moscow while trying to evade U.S. justice.

Sergey Lavrov says Snowden hasn't crossed the Russian border and insists that Russia has nothing to do with him, his relations with U.S. justice or his travel plans.

Speaking at a news conference today, he angrily lashed out at the U.S. demands for the extradition and warnings of negative consequences if Moscow fails to comply.

Lavrov says that accusing Russia of "violation of U.S. laws and even some sort of conspiracy" with regard to Snowden is "absolutely ungrounded and unacceptable."

He wouldn't say where Snowden is. Snowden booked a Havana-bound flight from Moscow Monday but didn't show up on the plane.

Aeroflot says a Cuba-bound flight for which National Security Agency leaker Edward Snowden was registered has departed from Moscow, but he has not been seen on board.

An airline representative told The Associated Press that the Havana-bound flight has left Moscow. The representative, who wouldn't give her name as she wasn't authorized to speak to the media, said Snowden wasn't on the flight.

AP reporters on the flight couldn't see Snowden in the seat he booked or anywhere else on the plane.

The airline said earlier Snowden registered for the flight using his U.S. passport, which American officials say has been annulled.

Snowden arrived in Moscow on Sunday from Hong Kong, where he had been hiding for several weeks to evade U.S. justice. Ecuador is considering Snowden's asylum application.
